Alba Iulia’s star-shaped citadel is one of Transylvania’s most overlooked sights. The walls of this magnificently preserved citadel – the largest in Romania – enclose grand monuments and museums, glittering churches, and archaeological treasures. Over recent years, these attractions have been thoroughly rejuvenated and sprinkled with plenty of multilingual information. As the place where the agreement was signed to unify Transylvania with Romania, Alba Iulia is the natural focus of 2018’s centenary of the union. So it's no wonder the town has a spring in its step.

Outside the citadel, Alba Iulia is a busy, sprawling place with no shortage of Soviet-era concrete. It's a worthy stop if you’re travelling from Sibiu towards the castles of Deva and Hunedoara, or up to Cluj-Napoca and the Apuseni Mountains.
